R. villicaulis Koehl. — The cha gry “concave |.,”

not true of the strongly marked ‘‘ Midl a ee Poa the 1. of which

Midlands” is the R. Mercicus Bagnall, since described in this

8. R. thyrsoideus Wimm. — Quite recently Dr. Focke has 
thus named a Heref. plant of the Rey. A. Ley’s, and I have seen 
Notts and Linc. specimens, gathered by Mr. H. Fisher, that I should 
also refer to it. The following is a translation of Dr. Focke’s 
lately published description of this aggregate species :—‘‘ Lis. 
medium-sized, hatte s above, ne appressed white felt beneath, 
vetae. and coarsely often incise-serrate; term. narrow when 
ung, later senses ovate to Lisadi elliptic. Inflorescence long, 
Tere, scarcely narrowed upwards, rather gre with long branch- 
lets and ped. Fl. showy, white | or light pink. Tall handsome 
plants with striking beautiful pan.” The ‘‘species’’ is marked off 
from R. pubescens by its very high-arching glabrous furrowed st. and 
lis. often incised, and with more closely appressed white felt

Mr. hay ‘in the open’’ in 1892 has Its. rounder, much thicker,

R. festivus Muell. & Wirtg. — Dr. Fo sa writes that specimens 
I ey him of a plant which grows in some quantity on Crowell 
, Oxon, ‘match the dried original plants” of this “ species,” 
not, I think, a material point of difference, as the pet. of the 
Crowell plant are not of a dead white. By his latest arrangement 
he places festivus after R. gymnostachys, caren past it only i in the 
following terms :—“‘ Lts. green beneath, as a rule narrower than in 
R. gymnostachys ; term. senaeally ner Inflorescence as in th 
preceding species; rather less hairy. More like R. acne and 
R The Crowell plait § is, however, much more strongly 
armed and more glandular than any ordinary gymnostachys, while 
its long pyramidal panicles, poueh very similar, are broader, and 
its 1. et thinn nner and greener.
